Description

  The present invention relates to a vehicle rear warning light that is attached to the outer surface of a flip-up back door of an emergency vehicle such as an ambulance to alert other vehicles and pedestrians.

  In order to improve visibility from the rear when the vehicle is running or stopped, not only emergency vehicles such as ambulances, but also vehicles with back doors, in addition to rear warning lights such as tail lamps and reflectors provided on the rear of the vehicle Warning lights such as brake lamps and tail lamps attached to the outer surface of the back door are installed (see, for example, Patent Document 1).

  By the way, for example, in a night traffic accident, an operation such as bringing an injured person into an ambulance is performed with the back door of the vehicle flipped upward. For this reason, the above-described lamp attached to the back door faces upward of the vehicle and cannot irradiate warning light to the rear of the vehicle. Moreover, since the said operation | work is performed in the space behind a vehicle, the warning light from the rear warning light installed in the both ends of a vehicle rear surface may be blocked | interrupted by an operator. For this reason, it is difficult to ensure sufficient visibility of the vehicle behind the host vehicle.

JP 2000-203352 A (pages 1 and 2, FIG. 5)

  The subject of this invention is providing the vehicle rear warning light for improving the visibility from the back with respect to the own vehicles, such as another vehicle and a pedestrian, at the time of opening upward of a vehicle back door.

In order to solve the above problems, a vehicle rear warning light according to the present invention is installed on the vehicle outer surface of a flip-up back door of a vehicle , and is a plate-like base member fixed to the vehicle outer surface , A first planar light emitter that is attached to the base member and that is attached to the base member so that the warning light emitted in the fully open state of the back door includes a horizontal component behind the vehicle; and A second flat light emitter that is formed separately from the single flat light emitter and is attached to the base member, and the attachment angle to the base member is adjusted so that the irradiation direction is the rear of the vehicle when the back door is closed. and characterized in that it comprises and. Thus, in the state where the fully open vehicle back door upward, the first plane light emitter is irradiated with警光rearward, and in a state of closing the back door, the second planar emitters vehicle rear Since the warning light is emitted to the other vehicle, it is possible to make another vehicle or the like recognize the own vehicle from the rear regardless of the open / closed state of the back door . In addition, by using a flat light emitter, it is possible to omit a reflection mirror and a rotation driving unit that are necessary for a conventional diffused warning lamp, and thus the warning lamp can be made compact. Therefore, even if the warning light is installed on the vehicle outer surface of the vehicle back door, it does not protrude greatly from the vehicle, and the vehicle can be moved backward or parked smoothly (claim 1). The planar light-emitting body is constructed by arranging the light emitting element, such as a plurality of LED on a plane (claim 4).

In addition to the first and second flat light emitters, a third flat light emitter whose irradiation direction is the side of the vehicle in a closed state of the back door is provided (claim 2 ), so that the side of the vehicle is visually recognized. It becomes possible to ensure the sex.

In addition, a drive circuit that individually switches on / off states of the first and second flat light emitters, and a switch for switching on / off states by the drive circuit when the fully open state of the back door is detected. further comprising a detection means for transmitting a signal to the drive circuit, and turns on the driving circuit, when the back door and fully open state, the first plane light emitter from off to receiving the switching signal from the detection means switching state, and, by configuring to switch to off state from the on state to the second planar emitters, it is possible to reduce power consumption by turning off unnecessary planar light emitters (claim 3) .

The vehicle rear warning light having the above-described configuration is mounted on the vehicle. At this time, the warning lights can be provided as a pair of left and right on the vehicle back door so as to function as vehicle width lights (claims 5 and 6 ). .

  As described above, according to the vehicle rear warning light according to the present invention, the first flat light emitter is arranged on the vehicle outer surface of the vehicle back door, and the warning light is emitted rearward when the vehicle is opened. For example, in an ambulance, the safety of carrying-in / out work at night can be improved.

  In addition, since a flat warning light is installed on the outer surface of the vehicle, other flat light emitters (second and third flat light emitters) can be provided to irradiate warning light in multiple directions other than the rear. The visibility is further improved. Unlike the present invention, when a warning light is installed on the inner surface of the back door, the warning light from the inner surface of the back door is blocked by the head (helmet) of an operator who works in the open space of the back door. There is a fear. Therefore, if it arrange | positions to a vehicle outer surface, a vehicle back can be irradiated reliably, without incurring such a disadvantage.

  Embodiments of the present invention will be described below with reference to FIGS.

  FIG. 1 is a diagram showing a vehicle on which a vehicle rear warning light according to an embodiment of the present invention is installed. The vehicular rear warning lamp 1 is used by being mounted on an emergency vehicle 2 such as an ambulance.

  In the emergency vehicle 2, a diffused warning light 4 is arranged on the vehicle side surface 3 as a warning light. On the other hand, a pair of vehicle rear warning lights 1 are installed at arbitrary positions on the outer surface of the flip-up type back door 5 of the emergency vehicle 2, for example, on both sides of the lower portion of the back door 5 separated in the vehicle width direction as shown in the figure. The

  FIG. 2 is a front view of the vehicular rear warning light 1 (a view of the vehicular rear warning light 1 attached to the emergency vehicle 2 as viewed from the rear), and FIG. 3 is a perspective view thereof. The vehicle rear warning lamp 1 is configured by attaching a plurality of planar light emitters having different irradiation directions to a substantially rectangular plate-like base member 6. As the plurality of planar light emitters, in the present embodiment, a configuration in which the first to third planar light emitters 7a, 7b, and 7c are unitized is illustrated.

  Of these, the first planar light emitter 7a is mainly intended for rear irradiation when the back door 5 of the vehicle is opened. In this example, when the back door 5 is closed, its normal direction is slightly lower than downward. The case where it inclines upward and is installed is illustrated (refer FIG. 4-A). This inclination angle takes into account the opening angle of the back door 5 when fully opened so that the irradiation direction of the first planar light emitter 7a is substantially backward when the back door 5 is fully opened (FIG. 4-C). Determined.

  The second flat light emitter 7b is mainly intended for back irradiation when the back door 5 is closed. In the present embodiment, the second flat light emitter 7b is disposed between second flat light emitters 7c and 7c, which will be described later, and the back door. The case where the normal line direction was turned to the vehicle rear at the time of closure of 5 is illustrated. The third planar light emitter 7c is for side illumination of the emergency vehicle 2. In this embodiment, the third planar light emitter 7c is disposed on both sides in the vehicle width direction with the first planar light emitter 7a and the third planar light emitter 7b interposed therebetween. And, when the back door 5 is closed, the case where the normal direction is inclined slightly rearward from the axle direction is illustrated. These flat light emitters 7a, 7b, and 7c are integrally covered with a red transparent globe 10, for example.

  In the present embodiment, as shown in FIG. 3, the second planar light emitter 7b is disposed away from the base member 6 and in the vicinity of the upper edge of the third planar light emitters 7c and 7c. Thereby, the warning light from the second flat light emitter 7b can be irradiated without being blocked by the third flat light emitters 7c and 7c. Moreover, since the space enclosed by each plane light-emitting body 7a, 7b, 7c generate | occur | produces in the said vehicle rear warning light 1 by arrange | positioning as mentioned above, the below-mentioned drive circuit can be arrange | positioned in the space. it can.

  Each of the flat light emitters 7a, 7b, and 7c includes a flat mounting board 8 and a plurality of light emitting elements 9 (LEDs in this example) attached to the mounting board 8 in a collective state. In this embodiment, the case where the mounting substrate 8 is rectangular and the light emitting elements 9 are arranged vertically and horizontally is illustrated, but the shape of the mounting substrate 8, the arrangement mode of the light emitting elements 9, and the number of arrangements are arbitrary. . The light emission color of the planar light emitters 7a, 7b, 7c can be determined according to the use of the warning light (red in this embodiment). This light emission color causes the light emitting element itself to emit light and the globe 10 to emit the light emission color. It can also be obtained by coloring with.

  Each of the planar light emitters 7a, 7b, and 7c is individually switched between a lighting state (may be blinking) and a light-off state by a driving circuit (not shown). The drive circuit is incorporated into each vehicle rear warning light 1 and unitized, and the drive circuit may be a separate unit from the warning light and installed in a location (for example, a vehicle interior) different from the vehicle rear warning light 1. . Further, in addition to sharing one drive circuit for the two vehicular rear warning lights 1, 1, the individual vehicular rear warning lights 1, 1 can be controlled by independent drive circuits.

  Next, the operation of the vehicle rear warning lamp 1 during the transition from the state where the back door 5 of the vehicle is closed to the state where the back door 5 is fully opened upward will be described with reference to FIG.

  When the back door 5 of the vehicle is closed (FIG. 4-A), the first flat light emitter 7a faces downward of the vehicle. On the other hand, the second flat light emitter 7b faces the vehicle rear, and the third flat light emitters 7c and 7c face the vehicle side, respectively. Usually, the visibility of the host vehicle with respect to other vehicles is required in this state on the rear side and the side of the vehicle. In this case, the second flat light emitter 7b and the third flat light emitters 7c, 7c are used. Only the light is emitted, and a warning light is irradiated to the rear and side of the vehicle. At this time, since the warning light from the first planar light emitter 7a is unnecessary, it is turned off to reduce power consumption.

  When the emergency vehicle 2 such as an ambulance arrives at the destination, the vehicle back door 5 is operated in the rear of the vehicle, so that the back door 5 is in an intermediate state shown in FIG. And then fully opened upward (see FIG. 4-C). Accordingly, the downward first flat light emitter 7a faces the rear of the vehicle. By detecting the fully open state of the back door with an appropriate detection means, and transmitting a switching signal to the drive circuit to switch on (or flashing) the first flat light emitter 7a, a warning light is emitted to the rear of the vehicle. The Therefore, even when the back door 5 is in the open state, the visibility of the host vehicle from the rear of the vehicle by another vehicle can be improved and a sufficient warning effect can be provided. At this time, since the second planar light emitter 7b faces upward of the vehicle, power consumption can be reduced by switching from lighting to extinguishing.

  An angle sensor or the like can be used as the detection means. In addition, it is also possible to switch on / off the light emitters 7a to 7c by using an existing signal that can detect opening / closing of the back door 5, for example, an ON / OFF signal of a room lamp.

  According to the above-described embodiment, the first flat light emitter 7a is turned on when the back door 5 of the vehicle is fully opened. However, the first planar light emitter 7a can be turned on in an intermediate process until it is fully opened. Thereby, even when working in a state where the back door 5 is opened to some extent before fully opening the back door 5, visibility from the rear can be ensured. In such a state (the back door 5 is not fully opened), the first planar light emitter 7a faces slightly below the rear of the vehicle, so it is desirable to use an LED having a wide viewing angle as the light emitting element 9 as much as possible. . With respect to the second and third planar light emitters 7b and 7c, lighting / extinguishing positions can be freely determined from the same viewpoint.
